To evaluate the level of student understanding recorded after our tree-thinking intervention, we compared student tree-thinking skills between the two treatments and to those of first-year graduate students.
To assess the efficacy of the intervention we compared the intervention and control group on the mean length of sick leave after 12 months.
For each investigated preventive health intervention, we compared the physicians' opinions regarding the use of the interventions and their actual use, using the McNemar test.
For the first intervention, we compared mutant animals raised at 22°C (normal housing conditions) with those whose mothers were placed at 30°C 2 days prior to parturition.
14 In an 18-month intervention, we compared two budesonide therapeutic regimens with a control group treated with a fixed dose of disodium cromoglycate (DSCG).
To determine the degree to which the organization and components of care have changed due to the intervention, we compared reports of patients and healthcare professionals between the SC and CAU control groups.
To assess the effect of PITC and provision of ART in the paediatric department (the intervention) we compared quarterly uptake of HTC and ART in the period before the intervention has started (Q1 2003 to Q3 2004 data from Lighthouse only) with the uptake thereafter (Q4 2004 to Q4 2006, data from Lighthouse and paediatric department).
Because of the complexity of the cleaning procedure with disconnection and reconnection of the standard luer lock cap (referred as "intervention"), we compared luer lock caps with a "closed access system" consisting of a luer access split septum system with regard to process optimization (work simplification, process time), efficiency (costs) and hygiene (patient safety).
Following 26 weeks of dietary intervention, we compared Si concentrations of the serum, urine, tibia and soft tissues (liver, kidney and spleen) between animals on the Si-deprived diet and those on the same, but Si-supplemented, diet (via their drinking water).
